Invasive Crayfish Collaborators,
Session Description:
Crayfish play an important role in freshwater ecosystems. As native species, they are recognized as critical ecosystem engineers that structure habitats, recycle nutrients, and sustain biodiversity. As invaders, they are associated with concerns regarding their impacts on food webs, habitat stability, and the challenges they pose to management and conservation efforts. As crayfish species become more common in the retail trade, efforts continue to prevent new and subsequent introductions of potentially harmful non-native species. The dichotomy of impacts between native and invasive crayfish in ecosystems provides a valuable example to understand both the vulnerability and resilience of freshwater systems.
This session—Claws and Effect: Crayfish Impacts Across Ecosystems—will explore how crayfish shape ecological processes, influence community dynamics, and intersect with human management and conservation. Presentations will span native and invaded systems, emphasizing how crayfish ecology informs our understanding of disturbance, recovery, management, and watershed health. Contributions offering new insights into species diversity and distributions will also be encouraged.
By integrating studies of population ecology, behavior, management interventions, and community engagement, this session highlights how crayfish science can advance the 2026 meeting theme: building resilient watersheds and communities. Through this lens, crayfish serve as both a warning and an opportunity—illuminating how understanding species’ impacts can guide more adaptive and inclusive freshwater stewardship.

Abstract submission closes Friday, January 16, 2026
To submit your abstract, please visit the SFS Annual Meeting website and follow the abstract submission instructions once the portal opens.
We would be thrilled to have your work featured in this session and help showcase the growing body of research advancing crayfish ecology and management. Please share this invitation with colleagues who may also be interested.
A special session on crayfish will be held at the 2026 SFS Annual Meeting. Session organizers are now accepting abstract submissions. See the full message below for more details. Any questions can be sent to William Ota at otaw...@msu.edu.
We are excited to invite you to submit an abstract to our Special Session, “Claws and Effect: The Role of Crayfish Across Ecosystems,” to be held at the 2026 Society for Freshwater Science Annual Meeting in Spokane, Washington, from May 17th-21st. The meeting theme—Gathering to Build Resilient Watersheds and Communities—aligns perfectly with our session’s focus on the diverse roles of crayfish across freshwater systems.
